One way to do that in D is to use `alloca`, but that's an issue
because the memory it allocates has to be used in the same
function that calls the `alloca`. So you can't, e.g., use
`alloca` to alloc memory in a constructor, and that prevents
using it in a custom array implementation.
You can call `alloca` as a default argument to a function. The
memory will be allocated on the caller's stack before calling the
function:

I've just tested and it seems it works as a constructor default
argument too.
